Struct ListView 

pub struct ListView { /* private fields */ }

The records of an entity in a grid: search, filters, sorting and export come with it. Opening a row opens its form.

Implementations

impl ListView

pub fn new(session: Session, frame: Frame, view: ViewInfo) -> Self

The list of this view in the model, reading through this frame.

pub fn compact(self) -> Self

Only the rows and their headers, as tall as they need, for a few records beside a form.

pub fn row_action(self, action: GridRowAction) -> Self

A button at the end of every row.

pub fn cell_text(self, text: CellText) -> Self

Says what a cell shows, when its value alone is not it.

pub fn on_open(self, handler: OpenHandler) -> Self

What opening a row does, with its key. Its form by default.

pub fn filter(self, filter: Option<Criteria>) -> Self

Shows only the records that meet this, besides what the way picked to see the list asks.

pub fn sort(self, field: impl Into<String>, ascending: bool) -> Self

Orders the records by this field, after what was already asked for.

pub fn column_shape( self, shape: impl Fn(&FieldInfo, GridColumn) -> GridColumn + 'static, ) -> Self

Changes the column of a field: a template, a width, a summary, or one of its own.

pub fn implied(self, field: impl Into<String>) -> Self

Leaves out the column of this field, whose value is the same on every row.

pub fn grid_shape(self, shape: impl Fn(DataGrid) -> DataGrid + 'static) -> Self

Changes the grid before it goes on the screen, for what the list has no word for.

pub fn single_selection(self) -> Self

Only one row selected at a time.

pub fn plain_toolbar(self) -> Self

Leaves out the filter builder and exporting to files, for a screen that has its own.

pub fn remote(self) -> Self

Brings rows from storage as they are needed, for lists too long to read at once. Grouping needs the rows at hand, so it is off, and searching covers only fields with text.

pub fn source(self, source: ListSource) -> Self

Reads its records from this and not from storage, for what no storage keeps.
